I don’t want to be a mom :(

I have so much guilt for saying this but I hate being a mom. I feel so limited. And it doesn’t help that I’m single, so I feel like it limits me even more when it comes to dating. I want hobbies, I want a boyfriend, I want to live life. I hate staying at home caring for my baby and being alone, and I’m not even sure if I have the motherly instinct. It doesn’t bother me to go a few days without my son. He’s three months old. When he’s with his dad, I feel somewhat relieved. It makes me feel so bad about myself. I was diagnosed with PPD. However, how do I know that I’m not just depressed, but just not cut out to be a mom? Like why does it mean you’re depressed if you simply don’t want to be a mom? Not all women want to be mothers... that doesn’t mean that they’re depressed or unhappy with their life. That’s why I have so much guilt. I feel like only the baby makes me depressed but nothing else does. It makes me feel like a horrible mother wondering if I’ll always feel this way and if I’m better off giving my baby’s dad full physical custody and only seeing baby once a week and every other weekend. then again that makes me feel like a deadbeat because mothers aren’t usually the ones who have less time with the baby. I feel like something is just wrong with me. I have two friends who are new moms as well who cry if they’re even away from their baby for a few hours. That feeling is foreign to me. For the record, I take Zoloft daily and see a therapist once a week. In general I feel like myself, normal. I just don’t feel happy about being a mom. I don’t feel bonded to him at all.
